log4php not logging multiple classes - php

Question

How can I implement log4php in order to log multiple classes separately?
I have the following example for classes A and B:
class A{
private $log;
private static $instance;
public static function getInstance(): Db3
{
if (!self::$instance) {
self::$instance = new self;
}
return self::$instance;
}
function __construct()
{
Logger::configure('path/to/log4php.xml');
$this->log = Logger::getLogger(__CLASS__);
}
}
and also class B:
class B{
private $log;
private static $instance;
public static function getInstance(): Db3
{
if (!self::$instance) {
self::$instance = new self;
}
return self::$instance;
}
function __construct()
{
Logger::configure('path/to/log4php.xml');
$this->log = Logger::getLogger(__CLASS__);
}
}
This is the log4php.xml config:
<configuration xmlns="http://logging.apache.org/log4php/">
<appender name="A" class="LoggerAppenderDailyFile">
<param name="file" value="/path/to/logs/%s.A.log" />
<param name="datePattern" value="Y-m-d" />
<layout class="LoggerLayoutPattern">
<param name="conversionPattern" value="%date{Y-m-d H:i:s,u} %-15logger %-5level %msg%n" />
</layout>
</appender>
<appender name="B" class="LoggerAppenderDailyFile">
<param name="file" value="/path/to/logs/%s.B.log" />
<param name="datePattern" value="Y-m-d" />
<layout class="LoggerLayoutPattern">
<param name="conversionPattern" value="%date{Y-m-d H:i:s,u} %-15logger %-5level %msg%n" />
</layout>
</appender>
<logger name="A"><level value="DEBUG" /><appender_ref ref="A" /></logger>
<logger name="B"><level value="DEBUG" /><appender_ref ref="B" /></logger>
</configuration>
I need log4php to log class A and class B separately but for some reason it is not working if I do this:
$a=A::getInstance();
$a->test();
$b=B::getInstance();
$b->test();
Everything gets logged in the same file, not in yyyy-mm-dd.A.log and B.log
test() only has this line: $this->log->info('this is a test') in both classes.
